J. Gresham Machen,
Christianity and Liberalism
(1923)
“ There are doctrines of modern liberalism, just as tenaciously and intolerantly upheld as any doctrines that find a place in the historic creeds. Such for example are the liberal doctrines of the universal fatherhood of God and the universal brotherhood of man. These doctrines are, as we shall see, contrary to the doctrines of the Christian religion. But doctrines they are all the same, and as such they require intellectual defence. In seeming to object to all theology, the liberal preacher is often merely objecting to one system of theology in the interests of another. ”
